click_data.num_archived_logs_to_use (collection.cfg setting)

Description

This option allows the selection of the number of logs to use from each archive directory.

It can be useful to limit the click data that is included in indexes to a certain degree of recentness. This helps keep the search results as relevant as possible over collections with changing information. This option can be set to:

n, where the last n records from each archive directory (as determined by alphabetical sort of the click logs) will have their click data included in building the index.

all, where every available click log in the archive directories will have their click data included in building the index.

The logs are usually archived each time a collection is updated. This means that if your collection is updated once per day, then setting this option to '5' will include the last 5 days worth of click logs.
